Residential hybrid systems also know as heat pumps are becoming more and more common in the hvac industry. A residential hybrid system looks and operates much like a residential air conditioning system with one notable exception, it provides both heating and cooling. Ideally suited for milder climates a heat pump uses a process called heat transfer to move heat into the house for heating and out of the house for cooling. Residential hybrid systems are available in split systems, packaged and ductless split systems. Regardless of type, the basic heating function remains the same. Residential hybrid systems can be installed on any duct work system, and take the place of your existing air conditioner.
